Concrete and masonry; Types of Construction

It is a continuous reinforcing bar having a seismic hook at one end and a hook not less than 90-degree hooks with at least six-diameter extension at the other end. The hooks shall engage peripheral longitudinal bars. the 90-degree hooks of two successive crossties engaging the same longitudinal bars shall be alternated end for end.

• Reinforcing Steel Bars

• Stirrups

• Lateral Ties

• Crosstie

Planted Column is considered in design as:

Which among the following activities takes 21 days before Formwork Removal is implemented?

• Removal of soffit formwork to beams and slabs

• Removal of props to beams spanning up to 6m

• Removal of props to beams spanning over 6m

• Removal of props to slabs spanning up to 4.5m

When laying concrete, it is sometimes not possible to pour in one setting. It can be due to weather, time constraints, lack of materials or even by design. Hence, there will be a separation between old and newly poured concrete once concrete pouring resumes. What do you call this?

• Expansion Joint

• Contraction Joint

• Construction Joint

• Cold Joint

Slump test is done in fresh concrete in order primarily to determine:

• Workability & Consistency

• Water Content

• Elasticity

• Rigidity

It is the stress caused by an applied loads that tend to twist the structure.

• Shear stress

• Torsional Stress

• Normal Stress

• Compressive Stress
